I was just going to say something along the lines of "Yeah, I'm sure that most of us have done silly stuff like that in front of the mirror at home (along with the Bruce Lee/Van Damme stuff) when we were kids - but why the heck would someone upload it to YouTube for the whole world to mock?"

Then I read the video description and realised that this was intended to be sent in to his teacher. In that case, who's his Hanshi? Ashida Kim? ChosonNinja? In this case, I actually hope that someone awarded him a belt out of sympathy - I didn't need to see that belly.
